Abstract
A lamp device includes three resilient blades extended downward from a housing. The housing includes a lower peripheral flange extended radially inward and having an opening. A switch is secured to a panel of a plate which is fixed in the housing. A cover of light transmissible material is engaged in the housing and has a peripheral rib extended radially outward for engaging with the peripheral flange of the housing so as to be supported in the housing. The resilient blade is engaged with the peripheral rib of the cover so as to stably retain the cover in place.
